Plus you need to throw in a little "fudge" factor-usually 10-15%. so we have some more complex math here-multiplication AND addition:lol: Now it's getting complicated

If you attended a SynAudCon class, then you probably should have received the information on a CD.  You also should have received a membership that lets you access such information from the SynAudCon web site.  If you haven't attended, then it's probably one more incentive to attend!

Here's a very basic Javescript based calculator. Not sure if it's exactly what you're looking for, but it's a start.

I am not 100% about the specifics, but EAW has a ceiling speaker calculator based off their hardware specs.
